opening, With the attendant disadvantages.

Another object of this invention is to pro? vide a catch which will lioldinore firmly the greater the tension which is applied to it.

v Inv other Words, this invention overcomes those. Vdiiiiculties which are' commonA With many present types of snaps, in that when great tension is applied the snap loosens and the liool; member then straightens out.

Referring to the drawing Figure I shows one form of the catch which I have invented, the catch being in a closed position. Figure II shows a modified catch which comes Within the scope of my invention. F'gure III shows the form of my invention illustrated in Figure I, but With the housing i Ui partially broken away and the hook member in the process of being closed.

Referring to the drawing, (l) indicates the eye by means of Whichl the snap can be conveniently fastened to the cord, buckle, rope, or. .other member .to Which it is engaged.V This eye may be made of any desired Icontoury and form, but will be described in this specification as an eye Y A loop member indicated by (4) .in 'Figure I or (2) in Figure III is attaohedto oye member The loop is arranged to be unsymmetrical about its longitudinal axis .having its point of greater extension at (4) in Figure I or (2) in Figure III. A body member is slioivn engaging with eye (l) and loop member Body member is engaged with eye member (l) by means of hump (2A) Which engages with the side of body member (3). Body' member (3) is formed with an opening (6) which engages With hook member formed from one side of loop (4). In the process of engaging hook (5) in hole (6), it is pressed against Wall (l0)V of body member (3) and then drawn backward until it falls into depression (l1) as shown in Figure III. (9) indicates theangle or bend lconnecting hoolc member (5) and the loop.

In the alternative construction shown in Figure II an additional eye (7) is provided lnear the end of the elongated unsymmetrical loop. In this alternative construction leg (3A) of the loop engages With leg (4A) which is att-ached to eye (l). Engagement is accomplished by hook member (8). The body member in the case of Figure II serves merely to stilfen and reinforce eye member (l) and the loop.

Oneof the essential principles Aof mylin-` vention is the designof the loop Which is unsymmetrical about its longitudinal axis in such a Way thatone straight continuous side or leg extends to the point at which ythe strain is applied. l

The other side or leg of the loop carries the catch member and being o set from or unsyinmetrical with the straight continuous side Will carryv a relatively small portion of l the total load.

In other Words, if a load is applied between the eye member (l) and the extremity (4L) of the loop, the major portion of the load will be sustained by the straight 'con-iV tinuous long side and onlya very small portion by the short discontinuous side Which contains theliook.

This arrangementl naturally reduces theA tendency of the catch to become disengaged and overcomes a difculty which is fundamental with most catches of this class.

It Will be apparent that to open the catch a slight pressure applied on the loop Will,

release the corresponding members. On the other hand, when in service a direct pull would increase the firmness With which the catch is engaged.

-It Will be apparent the catchis simple to make, durable and easy to operate.

The device Which I have invented serves Many modifications of the disclosed struc-' ture will be apparent to those skilled inthe art and still come Within the spirit of this invention. For eXainple,the body member 1 fof otbeiobvous mater'alsa-H Without de-..
